1. A bipolar electrode arrangement adapted to coagulate body tissues and/or body vessels, comprising:
a first electrode group and a second electrode group which are insulated with respect to one another and which each have ribbon-shaped electrodes having proximal and distal ends;
the electrodes of the first electrode group being connected in an electrically conducting manner and the electrodes of the second electrode group being connected in an electrically conducting manner;the electrodes of the first electrode group forming bipolar electrode pairs with adjacent electrodes of the second electrode group; andthe distal ends of the electrodes of the first electrode group being connected to one another, the proximal ends of the electrodes of the first electrode group being connected to one another, the distal ends of the electrodes of the second electrode group being connected to one another, and the proximal ends of the electrodes of the second electrode group being connected to one another,wherein all proximal ends are axially displaceable along an axis relative to the distal ends so that the electrodes of the first and second electrode groups can be expanded from a relaxed position into an expanded position to form a balloon; wherein the first electrode group is arranged axially offset with respect to the second electrode group so that, in the expanded state of the electrodes, the envelope of the first electrode group lies outside the envelope of the second electrode group in a first axial region and inside the envelope of the second electrode group in an adjoining second axial region, and are adapted to coagulate body tissues and/or body vessels. |
